PHPNuke, where are subscription email addresses stored?

We are migrating a full phpnuke blog to wordpress, however we are facing a big problem as we can't find the table where the subscriptors email addresses are stored, we even have considered that these email addresses could be in some file and not a database???

Here is a copy / paste quotation from the referenced publication. I don't know how to make this answer any more clear.
